Raspberry Pi Default Username and Password

Your username and password are used for numerous things, including SSHing into your Pi from another machine. It is recommended that you change these defaults for security reasons. This short guide is a snippet, provided for reference purposes.

The Raspberry Pi single-board computer has had built-in Bluetooth connectivity since the release of the Raspberry Pi 3 in 2016, allowing you to connect wireless peripherals such as keyboards, game controllers, headsets, and more to your device.
If you don’t have a model of Raspberry Pi that has Bluetooth built-in, you can use a third-party USB adapter to add support. You may need to install additional software packages to do this, depending on the adapter you use.
If you're using using Raspberry Pi OS (previously Raspbian), then Bluetooth should be enabled by default, but you'll need to follow these additional steps to connect and set up your devices.
These instructions will work for Raspberry Pi OS users, including Raspberry Pi OS Lite, which lacks a graphical desktop environment by default.
